Figi is a View Similar to Fig. Ais inustratinga still different form of the invention. First, referring'to Figs. 1 to`1-2 of the Vdrawings, a burner head is indicated at 16 and is connected-by oil and atomizing agent tubes`17 ,-18, respectively, to a by-pass which is formed in separable sections 19, 2O that are'releasably clamped together by a yoke l V21 and screw 22. x The yoke 21 ispivoted at 23 to opposite sides'ofthe'section 19 and the screw 22fis screwed* through the yoke and has 'its inner end'engaging a seat 24 in the upper sidelof the section 20. Y

, The opposite sides of the section 2O are provided with screw threaded openings 25,

-26 and into saidopenings are screwed pipe lines27, 28, respectively,` the pipe 27 supi plying oil and the pipe 28 vsupplying anatomA izin agent such as steam or air. Theo en' ingf25'fadmits the oil to a passage 29 in the section 20, vand the opening 26admits the 4atomizing agentv to a passage 30 in said section. Thefpassages'29, 30 are separated from one another-by a horizontal upper partition 31, ahori'zontal lower partition 32, and' a verf tical partition 33 that' connects the partitions 31, 32. Thus, the oil enters the chamber 29-and passes upwardly, while the atoml izing agent enters the passageV 30 and flows downwardly. j Pipeline 27 connects with an oil strainer 34 which may be of any suitable construction, and accordingly, not necessary to illustrate and describe in detail herein. The pipe line 28 is connected to any suitable source, not shown, of steam or compressed air supply. The lines 27, 28 are provided, respectively, with valvesV 35, 36 for controlling the fluid that passes through said lines.

The section 2O is provided at the lower end of the passage'29 with a threaded opening 37 into whichis screwed a thimble 38 provided with an eXternal annular shoulder 39 between Vwhichand the under face of the section 20'. is interposed an internal flange 40 of a seat member 41 `is taperedito fit aftapfered seat 43 1 inthe wall of `anopening 44 inthe Vsection '19, said opening 44V communicatingwith f'a passage 45 in said'section 19. I vThe thimble 38 Vis 'provided with lanother external annular shoulder 46 which is Vspaced l from the shoulder-39 a distance that is slightly greater than the thickness oftheflang'e l the thimble so that acertain amountoflat- -eralmotion occur.betweeni;heys^eat mem -ber and the th1mble, thus enabling the VSeat `member 'toautomatically adjust itself so as to `axially aline with the seat 43, regardlessi l-the'sections 1-9, 20. The bottom of the section '20- i`sprovided withV another Vscrewthreaded opening47 that of contraction and' expansion ofTei-tler` of the wall .of 'an openingfflin the 'section- 19,

Ysage 52'in the section19. .u From Ythe foregoing it willA be readily'understood that both .seat members 41, 48 will at all times perfectly center within their seats,

regardless of contraction or expansionofthe sections. 19,j20, since the seat memberj 41 canA move laterally with respect'to the .thimbie 38 or the thimble 38 laterally withrespectto 'the seat member v41. I Y i* Communication may be opened between the passa-ges45, 52 byreason of a port 53 con;- necting. said passages, and thisjport-is controlled by a ,suitable valvef54 which is normally closed when the burner is iiroperation. To jclean the burner, the valve 54 will be opened, thus permitting steam vto flow through `the Voil tube 17 and through thefoil passages in. the burner head which will be hereinafter described. The tube 17 is screwed into a threaded opening 55 in the partition 56 that separates the'passages 45,52, said opening 55 thus communicating-with the passage 45. The outer tube 18 that carries the atomizing agent is connected 4-a union 57 'toV aV threadedb'oss 58 on the section 19, the tubelS 440, andthe seat member 41'is a loose yfit. on 1.190

said .opening 51 communicating with pas- 1105 at all times with the .ports 73, 74,'a`ll of said l' projecting into an opening 59 inthe box, for

opening communication with the passage 52. The union 57 is provided with packing 60 to prevent leakage.

The supply lines`27, 28 are secured by U- clips 6l and bolts 62 to a supporting plate'A "that may constitute a front wall plate of the furnace.

Thel burner follows: Y rlhe body of the burner head may be made head will now be described as 1n onel piece, if desired, but, in the present instance, said body is of sectional construcone end of the tube 17, and the passage 68 receives :the atomizing agent through a threaded opening 70 into which-is screwed the tube 18. It is to be particularly noted that the atomizing agent passage 68 extends along the upper sideof the head-sectionV 64 and that the oil'passage 67 extends along the lower side of said head section or, in other'words, beneaththe passage 68, thus materially shielding the oil against heat that may be reflected from the furnace onto the top of the head section 64.v Also, it will be noted that the oil tube 17 lies within the atomizing agent tube 18 so that the atomizing agent protects theV tube 17 from the heat radiated by the furnace. I* Y vThe sections 63, 64, I provide with fiat contacting faces 71, 72, respectively, and opening through the flatface 71 are ports 73, 74. Also opening through the flat face 72 are ports 75, 76 which are, respectively, alined ports being elongate so as to pass the atomizing fluid and the oil regardless ofthe angle at whichthe section 63 may be positioned with respect to the section 6 The head section 63 is provided with lower and upper passages 77, 78 that-communicate with the ports 73, 74 so that, inthis case also, the atomizing fluid passage`7 8 is above the oil passage 77, thereby entailing'that the oil passage is shielded by the Vatomizing 'Fluid from heat reflectedon the upper side ofthe head section 63 from 'the furnace'walls. In this instance, the faces 7l, 72 are held in close contact by a `bolt 761 which passes through solid hubv'portions 762, 763 of the head sections 63, 64, respectively, the hub portion 762 separating the port 73 from the port 74 and the passage 77 from the passage 78; and the-hub portion 763 'separating the port 75 from the port 76 andthe passage 67 `from the passage 68.' The port75 communicates with the passage 67 and the port 76 communicates with the passage 68. Y

The passage 78l-terminates at its forward end in a circular bore portion 79v and said bore portion 79 terminates downwardly in an annular shoulder SOagainst'which seats a chambered cylindrical member 81 which is provided with .a threaded stud 82 thatprojects yupwardly through the bore portion 79 and through an opening 83 inthe top of the head section 63. Onthe outer end of the stud 82 is threaded a nut 84'wherebyl the member 81y ispulled tight against the seat 80. I Y Y f f lThe member y81 is provided withaJ transversely extending passage 85 which communicates at its rear end with the passa-ge 77r so as to form, in effect, a `continuation of said passage77. Thevforward end of the passage 85 communicates with a transversely extending segmental slot 86 which, infturn, communicates at' its forward end with anv Iarcuate vertical oil discharging slot 87 v that .isf formed in the outer face'of a bushing 88 that surrounds a portion'89'of`then1ember 8l, said portion 89 being ofa reduced diameter. In other words, the upper end portion of the member 8l-is "provided with an external cylindrical flange 90 which fits va bore portion 91`of the head section 63, whereas f the reduced portion 89 leaves an` annulariecess in'which vis disposed-the bushing 88.

The bushing 88 is spaced somewhat from the flange 90 and said bushingl is provided with 'an externalfiange 92, which v"seats against a lower face V93 of the head section 63. Projecting downwardly from the member 81, axially thereof, 'is-y a threaded stud 94 on which is screwed a nut v,95`that bears against the under face of a ring 96 that is held against the lower end'ofthe-bushing 88 whichv projects some "distance below the face 93; Thefring 96 surrounds a reduced'V portion 97 of the nut 95. The lower end of the bushing 88 has a portion cut away to define an arcuate slot 98 lying between said bushing 88 and the ring 96, the atomizing iiuid being "adapted to discharge 'horizontally through said slot 98 so that the oil discharg ing through the arcuate slot 87 will impinge Y onthe stream of atomizing fluid as saidatomizing fluid issues from the slot 98. The upper face of the ring 96 is recessed at 981 Arnu-nicates with the'chamber 79 through a vertical port or ports 99 in the member 81, said ports 99 passing on opposite sides of the passage 85 and being separated therefrom, f

as isl clearly shown atomizing fluid as in Fig. 11. Thus, the it' passes downwardly l through the ports 99 protects the oil in rthe passage 85 from heat reflected from the fur- :slot 993 opening to the face 93 so that, in

the member 81 and bushingl 88 assembling,

v willfirst be telescoped and then the bushing,

withthe me1nber81 therein, will be slidinto the bore that is to receive it. y

The form of the invention illustrated vin Figs. 13and lllis very` little different from the-construction hereinbefore described and the partsthat are the .of those above described are indicated by the functional equivalent same reference characters with the addition vof the sufx a. In this form of the invention lthe verticalV arcuate slot 87a communicates vwith the slot 8600not'only, but it is extended upwardlypast the flange a of the member 81a so as, also, to communicate with anvarcu- ,ate opening 10() that is cut through said flange, thereby permitting a predetermined amount of atomizing fluid to discharge from .the bore portion`79a past the flange 90a into the upperend ofthe slot 87a. Because of `the atomizing fluid discharging under higher .pressure than the oil, it follows that, in this form' of the invention., the oil will be discharged from the slot 87a under a pressure substantially equal to thefpressurevof the atomizin'g fluid discharging from the slot 9860.

Consequently, the `resulting mixture produced at thecircular line oi" impingement of the vertically v'and horizontally directed streams will be directed aslant downwardly and forwardly from the burner, and this `angle of `discharge ofthe mixture.. will be governed more or less bythe ring 96a which extendshorizontally beyond the periphery of the bushing 88a. Thus the ring 96a is of larger outside diameter than the ring 96 hereinbefore described. In this instance, the ring 96a'is provided with a. downwardly and outwardly beveledv upper face 101, it being understood that rings with faces of varying degrees ofvbevel may be associated with the lhead section 63 so as to thereby control, at

least to some extent, the downward deflection ofthe combustible mixture.

Theform of the invention illustrated` in Fig. 15 follows very closelyv the construction illustrated in Figs. 13 and` 14 and the elements that function the same are indicated by the same-numeral portions of the reference characters with the addition of the suffix The only difference isthat the ring 96?) has that portionof itsv upper face 1015, that ex-v tends beyond the periphery of the bushing v885, substantially horizontal, thuspreventing The foregoing will makeV clear the construction and operation of the invention, and,

briefly stated, the operation is as follows: l

The bushing 88, 88a or 886, and ring 96,96@v

or 96?) having been installed, and the headsection 63having been suitably 'adjusted to the desired angle relative to the-section 64;, the valves 35, 36-will bek opened to admit the atomizing fluid and oil to the burner head by way of the pipe lines 27, 28, tubes 17 ,Y 18 and theV various passages hereinbefore described. In the event of the Vassembly being that illustrated in Fig. 19, the oil will discharge from the slot, 87 under relatively low pressure-1 and impinge on the, atomizing stream issuing from the slot 98, thereby producing anely atomized combustible mixture that is ignited and burned lin a mannerwell understood in this art. c

'In event that the assembly is that of Fig. 13, apredeterminedv quantity Vof the atomizing fluid will mix to some extent with the oil in the slot 87a and the oiland steam will discharge .from the slot '87al at the relatively high pressure of the steam. The downwardly directed oil and steam from the slot 87a will impinge upon the high pressure atomizing stream issuing from the slot 98a, thus further ymixingjthe atomiZing-fiuid and the-oil and atomizingthe oil,` and the streams impinge upon the ring 96a, thereby still further atomizing` the mixture.

In the event of the assembly beingthat of Fig. 15, the same results are secured as that described in connection with Fig.`13, excepting that the mixture will be discharged from theburner at right angles to the axis of the bushing 886. l

Special attention isv directed tothe conhereinbe'rore described whereby the bushing 8l is held tightly'againstthe head section 63, thus making it `impossible for air or steam to leak aroundv 'the ring and come in contact with the oil within the burner head.

Also, to be particularly noted, is the construction Vof the passage for the atomizing struction fluid at the top, the passage for the oil atk carbon Within that portiony ofthe burner,

thus making it difficult to clean. Y Another point tobe observed is that, be-

abo

cause of the particular construction ofthe head section 63, member 81, bushing 88, andV the studsV 82, 94: and nuts 84:, 95 for sepa'- rately holding the member 81 and bushing 88 assembled with the head section 63, access may be had to the lower chamber for the atomizing fluid without disturbing the upper chamber for said fluid, and, also, access may be had to the upper chamber Without disturbing lower chamber.

Because or" the construction providing for the atomizing fluid passing from the upper chamber through ports into the lower chamber and through the port 100 in the iiangev 98, thence into the upper portion of the slot 87a, all parts of the burner head are maintained at a temperature approximately that of the atomizing agent.
